A team of contractors has completed a risky underground mission to remove more than 60 tonnes of unstable rocks which threatened to damage one of the Coast’s most important pipelines.
Working through harsh conditions in a pitch black tunnel, contractors manually removed more than 60 metric tonnes of rock and soil from an underground tunnel, moving half a tonne at a time.
The 2.5-kilometre tunnel runs beneath the Blackall Range and houses a pipeline which transports water from Baroon Pocket Dam to the Landers Shute Water Treatment Plant in Palmwoods.
The pipeline, which is a critical component in southeast Queensland’s water grid, has the ability to transport 180 megalitres to the treatment plant.
